Jimmy and his team of plumbers and electricians were courteous, clean and worked quickly to replace our faulty high efficiency boiler with a new one. The foreman was also very knowledgeable on the unit. Richard the sales rep was also great and very responsive to all our questions before, during and after our project. I would recommend this company, check with them and definitely hire them again for future projects. Job well done!

Didn't end up doing the work because the advice was that I couldn't really do it with a small space. This was good advice

They took over a messy job-in-progress, delivered a clear estimate of the work required, got us on their schedule, and did a good job. Sticking with them for ongoing service, too.

These guys came in below everyone else as far as price. When I said that I have 3 other companies coming to give an estimate. Gary said â I know what these things cost. Itâ s my jobâ . He also said this is the bottom line price and it was not one penny more. After the install a pipe burst. Nothing to do with what they did. It was due to age. They came out and replaced it at no charge. I recommend them to everyone. Great job Gary and Mario.
